“…Recently, triboelectric nanogenerators (TENGs), based on the coupling of triboelectricity and electrostatic induction, have been quickly developed for harvesting mechanical energy with various advantages of low cost, high output, simple structure, facile fabrication, flexibility, and light weight . TENGs are able to convert irregular mechanical energy from different ambient sources into electricity and they can serve as self‐powered sensors for various mechanical motions, such as touch/pressure sensors, acoustic sensors, vibration sensors, speed sensors, biomedical sensors, and human motion sensors .…”

An intelligent human-machine interface (HMI) is a crucial medium for exchanging information between people and electronics. As one of the most important HMI devices, touch screen sensors are widely applied in personal electronics in daily life. However, as the most commonly used touch screen sensor, capacitive sensors can only detect limited kinds of gestures such as touching and sliding. Here, a triboelectric touch-free screen sensor (TSS) is reported for recognizing diverse gestures in a noncontact operating mode by utilizing the charges naturally carried on the human body. Compared with conventional capacitive sensors, the TSS is capable of detecting various gestures such as the drop and lift of finger with different speeds, making a fist, opening palm, and flipping palm with different directions. Based on the TSS, an intelligent noncontact screen control system is further developed, which is used to unlock the smartphone interface by the noncontact operating mode. This research for the first time proposes the concept that taking the human body itself to participate in triboelectric self-powered noncontact sensing and provides a touch-free design concept to develop the next generation of screen sensors. It can alter the usual way that people operating their personal electronics.

“…While most of the current HMIs are based on voices and physical contact motions, breath can also be an alternative interaction approach for HMIs, especially for disabled persons. Figure 7B shows the implementation of a breath‐driven single‐electrode TENG as a self‐powered HMI for the communication with various electrical devices 256 . The breath‐driven TENG is mainly composed of a flapping polyethylene terephthalate (PET) thin film and a bottom copper (Cu) electrode, which is able to generate responsive electrical signals with an incoming airflow from human breathing.…”

The past few years have witnessed the significant impacts of wearable electronics/photonics on various aspects of our daily life, for example, healthcare monitoring and treatment, ambient monitoring, soft robotics, prosthetics, flexible display, communication, human‐machine interactions, and so on. According to the development in recent years, the next‐generation wearable electronics and photonics are advancing rapidly toward the era of artificial intelligence (AI) and internet of things (IoT), to achieve a higher level of comfort, convenience, connection, and intelligence. Herein, this review provides an opportune overview of the recent progress in wearable electronics, photonics, and systems, in terms of emerging materials, transducing mechanisms, structural configurations, applications, and their further integration with other technologies. First, development of general wearable electronics and photonics is summarized for the applications of physical sensing, chemical sensing, human‐machine interaction, display, communication, and so on. Then self‐sustainable wearable electronics/photonics and systems are discussed based on system integration with energy harvesting and storage technologies. Next, technology fusion of wearable systems and AI is reviewed, showing the emergence and rapid development of intelligent/smart systems. In the last section of this review, perspectives about the future development trends of the next‐generation wearable electronics/photonics are provided, that is, toward multifunctional, self‐sustainable, and intelligent wearable systems in the AI/IoT era.

“…[205] Furthermore, HMI devices based on TENGs have been developed for both noncontact and tactile interaction. [196,206,207] Breath-based HMIs have been developed by Mao et al to realize household object control which is schematically illustrated in Figure 11a. [196] The TENG was activated by the breathing of the user and the signals were processed and transmitted to the appliance (Figure 11b).…”

Conventional bulky and rigid electronics prevent compliant interfacing with soft human skin for health monitoring and human–machine interaction, due to the incompatible mechanical characteristics. To overcome the limitations, soft skin‐mountable electronics with superior mechanical softness, flexibility, and stretchability provide an effective platform for intimate interaction with humans. In addition, soft electronics offer comfortability when worn on the soft, curvilinear, and dynamic human skin. Herein, recent advances in soft electronics as health monitors and human–machine interfaces (HMIs) are briefly discussed. Strategies to achieve softness in soft electronics including structural designs, material innovations, and approaches to optimize the interface between human skin and soft electronics are briefly reviewed. Characteristics and performances of soft electronic devices for health monitoring, including temperature sensors, pressure sensors for pulse monitoring, pulse oximeters, electrophysiological sensors, and sweat sensors, exemplify their wide range of utility. Furthermore, the soft electronic devices for prosthetic limb, household object, mobile machine, and virtual object control are presented to highlight the current and potential implementations of soft electronics for a broad range of HMI applications. Finally, the current limitations and future opportunities of soft skin‐mountable electronics are also discussed.
